The cam lock spring 112 is a torsion type of coiled spring with a straight leg 202 and bent leg 204. The bent leg 204 is ninety degrees to the coil 206 of the cam lock spring 112. A screw 208 is inserted into the screw hole 200 of the connecting body 196 and through the coil 206 of the cam lock spring 112. The screw 208 is then threaded into the threaded screw hole 172 of the cam side 122 of the drop rest mount 96. The cam lock spring 112 is positioned such that the bent leg 204 contacts and is tensioned against an inside surface 210 of the cam lock 108 between the connecting body 196 and the latch 198. The cam lock spring 112 is also positioned such that the straight leg 202 contacts and is tensioned against the cam lock spring roll pin 194. The latch 198 of the cam lock 108 is tensioned away from the cam 110 by the cam lock spring 112, but can be rotated toward the cam 110 under force. The cam lock stop roll pin 192 interacts with the connecting body 196 of the cam lock 108 and prevents rotation of the latch 198 to far away from the cam 110 and aids in retaining the tension relationship between the cam lock spring 112 and the cam lock 108.

FIGS. 12 show the arrow rest 106 in an arrow support pre-rest position. An arrow shaft 38 is supported by the arrow rest surfaces 154 of the arrow rest 106. The arrow rest 106 is retained in the arrow support pre-rest position by the arrow rest locking system. The arrow rest spring 104 biases the arrow rest 106 away from the arrow shaft 38 and therefore the arrow rest locking system is used to retain the arrow rest 106 in the arrow support pre-rest position. Pulling back on the arrow rest 106 by pulling the tension string 18, which pulls the lug 146 and rotates the arrow rest 106, allows the user to move the latch 198 to engage the latch groove 184 of the cam 110, as shown in FIGS. 4 and 13. The arrow rest 106 is locked into the arrow support pre-rest position, when the latch 198 is engaged with the latch groove 184 of the cam 110. The arrow shaft 38 can be placed onto the arrow rest surfaces 154 of the arrow rest 106. When the user pulls on the drawstring 24 of the archery bow 12, the tension string 18 pulls on and rotates the lug 146. The rotation of the lug 146 caused the arrow rest 106 to rotate back further to an arrow resting position. The arrow resting position is the desired position of the arrow rest 106 prior to firing of the arrow. The rotation of the lug 146 also causes rotation of the cam shaft 98, which in turn rotates the cam 110. This rotation of the cam 110 causes the latch 198 to disengage from the latch groove 184 and move away from the cam 110 due to the cam lock spring 112 biasing the latch 198 away from the cam 110. When the user releases the drawstring 24, the tension on the tension string 18 is released and the arrow rest surfaces 154 of the arrow rest 106 move forward and downward due to forced rotation of the connection end 158. The connection end 158 is forced to rotate due to the arrow rest spring 104 causing the string lug 102 to rotate. Whereby, rotation of the string lug 102 causes the arrow rest washer 100 and the connection end 158 to rotate due to the interconnection with the string lug 102, arrow rest washer 100 and the connection end 158. The arrow rest 106 can also be pulled to the arrow resting position without the use of the arrow rest locking system, simply by pulling back on the drawstring 24, which in turn pulls on the tension string 18 and rotates the arrow rest surfaces 154 of the arrow rest up and back. One of the advantages of the present invention is that the arrow rest surfaces 154 move away from the arrow shaft 38 faster. The arrow rest surfaces 154 move away from the arrow shaft 38 faster, because the rotation point of the connection end 158 is at the lower extension, which is the lowest point on the drop rest assembly 10 in relation to arrow resting position. Units currently on the market have a higher rotation point.

While different embodiments of the invention have been described in detail herein, it will be appreciated by those skilled in the art that various modifications and alternatives to the embodiments could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements are illustrative only and are not limiting as to the scope of the invention that is to be given the full breadth of any and all equivalents thereof.
